I've got a Kenmore 587.15173400 dishwasher. We noticed the bottom arm sprayed well but the top arm wasn't rotating or spraying since insufficient water was being pumped up there to power it. I changed out the pump but it made no difference. I discovered by accident that if I opened and closed the door quickly while it was washing that suddenly the pump pressure would increase dramatically and the top arm would get plenty of pressure. So, it appears the pump has more than one speed, which I didn't know. My question is why would opening and closing the door quickly cause the pump to increase and why isn't it running at this higher pressure when washing as it obviously should be?

decrete, you want to get down to the chopper and screen. If the screen is plugged up with gunk there won't be enough pressure to reach the top spray arms. Check out the posted pics. Remove the lower spray arm. Rotate the rear feed arm to the right until it unsnaps from the tube going up the back. See the 4 torq screws holding the filter on. Remove them. Lift the filter up. Now you will see the chopper inlet cover. 1 torq screw holding it in. Lift it up and there's the chopper and screen. Catriver..post back

Hi: I just posted a similar problem, but found a solution. After taking the arm, etc. apart (and verifying no blockages), I thought maybe the lack of water pressure was being caused by the fact that there are TWO holes for the top spray arm (higher and lower rack setting) on my model. ie. that water was being forced out of both holes, causing a drop in water pressure, which was causing the top spray arm to stop spinning. I plugged the unused hole with a wine bottle cork (to keep the water from spraying out the unused hole), and voila, it now works.
I wish all appliance fixes were this easy...!

On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.
But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.
If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.
Watch for error codes on the display and report back what you find, OK?
Good Luck!
